Problem/activity:
Find the general solution for:
$${\mathrm{cos}\left({\pi\over2}+x\right)=\mathrm{tan}{\pi\over4}}$$


Standard options: 
A. Prove the Pythagorean identity sin^(2)(θ) + cos^(2)(θ) = 1 and use it to find sin(θ), cos(θ),or tan(θ) given sin(θ), cos(θ), or tan(θ) and the quadrant of the angle.
B. Prove the addition and subtraction formulas for sine, cosine, and tangent and use them to solve problems.


Thought: An initial step when solving for x in this problem requires the use of the addition formula for cosine on the left side of the equation. Solving this problem does not require use of the Pythagorean identity.
Answer: B

Now, assign the following problem or activity to one or more relevant standards it aligns with.

options: Use volume formulas for cylinders, pyramids, cones, and spheres to solve problems.

Give an informal argument using Cavalieri’s principle for the formulas for the volume of a sphere and other solid figures.

Give an informal argument for the formulas for the circumference of a circle, area of a circle, volume of a cylinder, pyramid, and cone. Use dissection arguments, Cavalieri’s principle, and informal limit arguments.

Three of the great Egyptian pyramids are pictured below. Each is a square pyramid.

Calculate the missing information for each the 3 individual pyramids based on the given measurements:
The great Pyramid of Menkaure has a height of about 215 feet and a base side length of about 339 feet. What is its volume?
The great Pyramid of Khafre has a volume of about 74,400,000 cubic feet and a base side length of 706 feet. What is its height?
The great Pyramid of Khufu has a volume of about 86,700,000 cubic feet and a height of 455 feet. What is the length of its base?
The Great Pyramid of Khufu once stood 26 feet taller than it is today. Calculate the original volume of the Great Pyramid. Similarly, the Pyramid of Khafre has eroded over time and lost some of its height. If the original volume of the pyramid was approximately 78,300,000 cubic feet, what was its original height?
